About Carlson Labs - Vitamin K2 as MK-4 60 capsules

Carlson Labs Vitamin K2 as MK-4 delivers menaquinone-4, the bioactive form of K2 found naturally in animal-based foods, to support bone metabolism and cardiovascular health. MK-4 works by activating proteins that help direct calcium to bones rather than soft tissues, making it a practical option for adults focused on skeletal and arterial wellness.

Why It's Worth Considering: Carlson uses the MK-4 form specifically, which has a well-established research profile in bone health studies, and the brand maintains a long-standing reputation for quality manufacturing and third-party potency testing.
